GLASS-WORKING: MACHINE.

Specification of Letters Patent.

To all whom it may concern.:

Be it known that I, MrNo'r K. HOLMES, a citizen of the United States,residing at Muncie, in 'the county of Delaware an have invented a new anuseful Glass-Working Machine, of which the following is a specification.y

The object of my invention is to produce a glass working machine for theproduction of pressed glass articles in which aA portion of the pressingmember is allowed to remain within the glass for more or less of aperiod subsequent to the withdrawal of the mechanism by which it wasassociated with the molten glass. f

The accompanying drawings illustrate my.

invention.

Figure 1 is a central vertical section (on line 1.1 of Fig. 2) ofa'machinJ embodying my invention and especially designed for theproduction of glass insulators of a well known type, said inachine beingof the general type disclosed in Patent No. 909,5952 Fig. 2 is ahorizontal section on line 2H2 o Fig. 1; Fig. 3 is an enlarged verticalsection on the line 3-3 of Fig. 4, showing the ress plunger inglass-forming position and in stud receiving position; Fig. 4 afragmentary section on the line 4--4 of Fig. 3 Fig. 5 a sectional detailon line 5-5 of Fig.' 6 of the mechanism for advancing the stud magazine;Fig.- 6 is an elevation of parts shown in Fig. azine being shown invertical section said section being taken on line 6--5 of Fig. 1,- themagazine, however, 'being shown in vertical section; Fig.- 7 -afragmentary detail on line the mold table-driving vertical sectiontrain; Fig. 8 a-fragmentary Fi 9 a section on the line 9--9 of Fig. 8.

In the drawings, 10 indicates a supporting carriage of the usu l formcarrying a supportin table 11 in the upper face o which is Iormed anannular groove 12 in which is rotatably mounted" an annularvmold-carrying table 13 upon which molds 14 'of any type are mounted.lThe moldtable 13 is intermittently advanced step-by-step, in thedirection indicated by the, arrow in Fig. 2, by any suitable means. tureshown in the drawings the annular table 13 is provided with gear teeth15 on its outer periphery engaged by a gear wheel 55 16 carried upon theupper end ofthe shaft 5, the' supporting table and the mag- A g on line8-8 of Fig. 1 of the mold table lock;l

In the struc-'f means of 17 to the lower end of which is attached abevel pinion 18 meshed with a similar pinion 19 upon one end `of a shaft20 haging a pinion 21 at its opposite end, and this piny ion "21 is inthe path of movement of a segmental ogear 22 carried by the main drivingshaft 23, the parts being so proportioned that each complete revolutionof the main driving shaft 23 will produce one advancement of themold-carrying table, vin the usual manner. Shaft 23 is continuouslydriven by any suitable means such as worm wheel 24 and worm 25, saidworm 25 bein carried by a shaft 26 connected by gears 2% and 28. with amotor 29 mounted upon carriage 10. f

Extending upwardly from table 11 are two guide rods 31 and` 32.Journaled upon rod 31 is a hollow shaft 33 provided with a gear 34 atits lower end and this gear meshes with a pinion 35 carried by the up erend of a shaft 36which is journaled in ta le 11 and is provided at itslower end with a bevel pinf ion 37 arranged in the path of movement of asegmental gear 38 mounted on the shaft 23. Mounted upon the hollow shaft33 is a sleeve 39 upon which is journaled fa transfer arm 41 andthisvtransfer arm.- is splined on the sleeve 33 by means of a plate 42attached to the under side of arm 41 and holding it in lace upon sleeveI39. rlhe sleeve 39 pro- )ectsv upwardly through one end of thepluner-head 43 and at its upper end is threaded to receive a collar 39which will engage the plunger head and thus permit the transfer arm 41to beadjusted so as against the under side of the plunger head.

.The opposite 'end of the plunger head y,is

bored to receive the post 32 so 'that the post 32 thus becomes avertical guide for the vertical movement of the plunger head.

The plunger head may be reciprocated by any desired means. In thedrawings it is shown as provided with an upwardly projecting threadedstem 51 which is firmly secured to the head 43 at its middle'. Adjustablmounted upon the stein 51 is a nut 52 which serves as an abutment for a'spring 53 which is interposed between thenut 52 and v an operatingcrosshead 54 slidably mounted` -upon the guide rods 31 and 32. Head 54is reciprocated through a uniform stroke by adever 55";pivoted Patented.aeg. a'ieie. s

to lie 'closely at 56 on the lower end ofa link 57 pivoted at 58 uponthe' upper endof rod 3,2. Connected to lever 55 11o".

-end of stem 51 is a link 59 which is connected to the upper end of apiston rod 60. Piston 60 is reciprocated by means of a pitman rod 61carried by a crank pin'62 of a disk 63 carried by shaft 23. Slidablymounted upon the lower is a plate 65 which projects beyond the sides ofplunger carries at each end a depending rod 66. At the lower ends of thetwo rods 66 is secured a ring plate 67 formed to close the upper ends ofthemolds 14. Arranged between plate 65 and nut 52, in a well knownmanner, is a spring 68 by means of which the ring plate 67 will be heldevenly in place upon the molds.

It is desirable to lock the mold-carrying table 1n its successivepositions during thepressing action and for this purpose I vide alocking pin 71 yieldingly urged upwardly into table-engaging pos1t1on,1n

properly formed holes 72 formed in the by springs 73.

In order to advance the magazine 82 step-by-step, Isecure to the lower end of shaft 81 a ratchet wheel 91 provided with asmany teeth as there are pockets 83. Pivoted upon shaft 81 is apawlcarrying arm 92 pro-vided with a pawl 93 arranged to engage Arm 92is reciprocated by means of a link 94 attached to a block 95 adjustablymounted upon a rod 96 slidably mounted in brackets Secured to rod 96 isa block 98 to which one end of a link 99 is pivoted, the opposite end ofsaid. link being pvoted to one end of a lever 101, and the opposite endof this lever is-pivoted to an arm 102 mounted upon an eccentric 103carried by shaft 23.

erably formed plunger.

projection mal to serve as a glass-forming This Stem is therefore formedfor through the ring 67 and the nors sufficient to permit the Y togetherwith anything which it may carry at its lower end, to swing betweenthese two plates. Stem 110 is hollow so as to receive the upper end ofany one of the studs 84 d in order to yieldingly hold the stud 84 withinthe stem 110 I provide a yielding gripping finger 111 adapted to engagethe stem of a stud 84. Finger 111 is adjustably mounted upon a rod 112which is carried by, and lies transversely to, the stem 110. Rod

112 is provided at one end with a head 113. i

Beneath this head I arrange a spring 114 normally urging linger 111toward the aXis of stem 110. Adjustably mounted upon the opposite endofrod 112 is a button 115 which may be so arranged as to be engaged by.the beveled upper end of a fork 116, carried by plate 67, in such mannerthat, when the parts are in the position shown in Fig. 3, inger 111 willbe withdrawn from the stem of stud 84. It will be readily understoodthat arm 41 may be multi-ended with each end, provided with a stem 110,in which case its rotative advancement each time would be Adetermined bythe distance between its ends.

In order that the transfer arm 41 may not shaft 33, I form 1n each endof this arm a notch 117 adapted to receive a spring latch 118. Thislatch 118 is provided with a pair of oppositely projecting pins 119(Fig. 4) which, when the presser head 43 is moved upwardly, are engagedby stationary lingers 120 which act uponl the pins to withdraw latch 118fromthe transfer arm 41.

In operation, molten glass is deposited Within the molds at points F(Fig. 2) by any suitable means and. magazine 82 is lled or partiallyllled withy the desired numberof studs 84. By vertical reciprocation 'ofthe presser head 43 one of the stems 110 will be brought down upon theupwardly projecting end of one of the studs 84 and, when the presserheadrises, this stud will be withdrawn from the magazine. As the presserhead 43 rises, plate 67 will remain in position upon a mold untilthepresser head engages the plate 65. At about this time the segment 38'will come into -mesh with pinion 37 thus rotating shaft 36 and thehollow shaft 33, giving said shaft 33 half rotation and bringing thestem 110, into which a stud 84 has been inserted, directly beneath thepresser head 43, at which time latch 118 engages the transfer arm 41 tohold it in lace. At about the same time segment 22 will engage pinion 21and operate to rotate gear 16 and advance the mold table one step. Atabout the same time eccentric 103 will cause a'movement of the partsconnected to -t in ,such manner as to swing the arm 92 and advance themagazine 82 one step. Thereupon, the freshly illed mold having beenbrought beneath the plunger by the advancement of the table, the presserhead 43 -will be again reciprocated and the new stem 110 with the studwhich it contains at its lower end, will be projecteddownwardly, ring 67moving into position at the upper end of the mold and then the presserhead continuing in its downward movement so as to project the .stud 84and the pin 110 )through ring 67. Just before this downward movement iscompleted, he opposite stem 110 embraces a new stud 84 and the fork 116engages the button 115 of the rod 112 of the stem 110 so as to retractfinger 111 from the stud 84 which is within the molten glass so that,when the presser head again moves upwardly, the stud 84, which has justbeen projected into the glass, remains in the glass and is carried awaywith the completed article when the mold table is again advanced. l. y l

Any suitable means may be provided for extracting the studs 84 if theyare to be extracted. Table 11 may carry a mast or standard 121 providedwith cross arms 122 in which is mounted a shaft 123 capable of rotationand vertical reciprocation. Shaft 123 carries a chuck 124 at its lowerend formed to receive the exposed stem of stud 84 and also carries ahand wheel 125 by means of which the shaft, and consequently the stud,may be rotated so as to unscrew tne stud from the glass which, by thistime, has` hardened.
